Default Adjustiing/mod'ing digital thermostat on LG window air conditioner

If I may venture a stupid question, are you sure that the thing isn't simply

Or even if that's the way that particular unit was made, since the OP
just bought it, why not just take it back and get one from another
manufacturer? I would think someone must make one that goes below 68.

As a kludge, it sounds like the small power resistor secured to the
temp sensor and controlled by a thermostat located elsewhere would
work. You'd have to do the math, make sure the thermostat could
handle the current or use a relay, use low voltage (12V) for safety,
etc.


Not a stupid question at all. I'm planning to at least swap out this
one today, I just wanted to get some input in case the 2nd example
performs the same way. The problem is this wasn't a typical double hung
installation, the window is a large (tall but narrow) panel which swings
out vertically, I had to remove the window (large, heavy, 2nd floor, no
outside access) & make & install a plywood panel of the right dimensions
to go above the unit. In other words, taking the damn thing out &
putting it back in is a major PITA. I could try another brand, but I'm
not guaranteed it won't behave the same way (it's been at least 7 years
since I had to deal with a window AC, I thought perhaps this was "just
they way they are now", that maybe they won't go any lower for energy
concerns or something) and if its size is different it may require
modifying what was a fairly troublesome installation, especially if it's
shorter & I have to cut/paint another longer plywood panel. Too bad the
mother couldn't just WORK the way I wanted out of the box, (really, I
don't think expected lower than 69 is too much to ask) but alas things
don't seem to go that way for me too often... ;-)

Thanks also for the suggestions on a work around.
